' ATO all whom i may Be it known that I, IosP l?EARsO1\T ROG-I ERS, ofythe cityof Toronto,in,the county of; York and Province of Ontario,Canada; have invented a certainf new and yuseful Oil-Canl andLamp-Filler,.of which-the' following isa specification. .1 f f, I

Theobject of the invention is ,toprovide a` cheap, simple, clean, andeffective device for filling lamps and other receptacles withoil by`means of air-pressure andinsuring a steady. flow of oil, which maybereadilyfchecked; so` as to prevent any overflow; and it'consists, e..`

lsentially, of an oil-can provided with an air` pump cylinder,in whichis I tteda piston-head withy an air-valve, and means for jadmitting airto the lower part of the air-'pump cylinder below the piston-head, and ahollow'pis'ton-rod having an open upper end, also a flexible airtube,forming acommunic'ation between the interior of the can above the oiland the interior of the hollow piston-rodfabovethe upper surface of thecan, the open upper end of, the piston-rod being closed byfthe lingerwhen theI pump is being operated 'and while the oil is flowing-throughthe ejecting-pipe, the finger being removed when it isfdesired tocheckthe fiow, as hereinafter more particularly described, and thendefinitely pointed outin the claims. l r l Figure l is a perspectiveview partially in section and broken'` away to expose the interior ofthe can. Fig. 2 isaperspective detail of the piston-head, the valve,andvalve-seat shown in-Fig. 1. Fig. 3 is a idetail showing the top ofthe oil-ejecting pipe, itsY mode of connection, the eccentric opening,and the waste-oil chamber. Y

Like letters of referencegf/indicate similar parts in the dierentfigures.

In Fig. 1, A is'the bodygot1 the can. ware bosses formed thereon, andbisthe bail or the handle. V n .y l

B is a beveled rim wherebythe top of the can is preferably countersunk.

C is a screw-cap covering the hole through which the oil is poured intothe can.

D is an'. oilejectingf pipe .which passes through anorice S, ,which islarger than the diameter of thepipe D, which latter is fitted fintotheupper end of the'oil-ejecting tube D',

the pipe D andejectingetube D forming, when tfitted together,an,oil'-ejecting pipe. (See Figs. .l and 3.

The'oriti'ce; S is eccentric with relation to the pipe' D, and s is apin for keeping-thepipe in place; T is a waste-oil chamber formed by,`enlarging the top of the eject- `ing-tube D, andwhichis secured to thebottom of the top of thecan.

It isa groove or gutter formed in the top of the can for conveying wasteoil through the eccentricorice S to the waste-oil chamber T.

By turning `the bent end of the ejectingpipe D the pin s may come underthe wide end of the eccentric orifice S and the pipe D may be withdrawnfrom the ejecting-tube D', so as to allow the oil in the waste-oilchamber T to flow down ,the ejecting-tube D. f

d is the inlet to the oil-ejecting tube D vand is located near thebottom of the can,

.of the hollow piston-rod H. This stem F is made hollowjso as to admitpfinstant relief of air-pressure inltheinterior of the can, so as tocheck; the new ,cfaoil when thenger is removed from., thej ,hollowpiston-rod, as hereinafter vreferred to.,l Thislexible tube F is madesuliiciently long to permit of one end Y thereof rising and falling withthemotion of the hollow piston-rod H.

G ris an air-pump cylinder which v passes through and is soldered tothetop of the oilcan A. The upper portion above the surface of the canis screw-threaded, and thereon is screwed the cap g, through which thehollow piston-rod passes and is loosely fitted, so as to permit ot' thepassage of the air to the interior of the cylinder.

The hollow piston-rod II is provided with a piston-head I and auair-valve L. This hollow pistou-rod is open at h. then the piston-rod isboing forced up and down in order to pump air into the upper part of thecan the hole h is closed by the finger, which may be removed when it isdesired to allow the compressed air to escape from the interior of thecan, as hereinafter described, and thus to stop the iiow of oil.

O is the valve-stem which is tted to the valve L, and which is adaptedto move in the airway N.

Fig. 2 shows a detail off the valve and piston-head, in which L is theair-valve, which is adapted to tit down on the seat M when the valve isclosed. U is piston-packing, and v is a spring for pressing the packingagainst the side of the cylinder in the usual manner, and K is aiiangefor holding the packing. In this view, Fig. 2, the Valve is shownopen, the face being raised from its seat, as on the downstroke of thepiston, the air passing through to the interior of the hollow pistonrodfrom the bottom of the cylinder.

In Fig. 1 is seen the method by which the air is admitted to the bottomof the cylinder below the piston-head I, in which V is a pipe whichcommunicates with the interior of the pump-cylinder G near its top andwith an airchamber W. The top of this chamber is provided with orificesand valve L similar to those in the piston-head I, so that when thepiston-head I is being raised the air is drawn through the pipe V to theairchamber vW and, raising the valve L from its seat and passing throughthe orificesF and the airway of the valve, enters the lower part of theair-chamber. IVhen the piston-head I descends, the valve L becomesclosed, the valve L in the piston-head opens, and the air is forced intothe interior of the hollow pistonrod, and thence, by means of the hollowstem F', the fiexible tube F, and air-inlet pipe E to the air-space overthe oil Q within the can, the finger all this time remaining over theupper orifice h in the hollow piston-rod H, so as to prevent the escapeof air. After several strokes of the hollow piston-rod II the air may besufficiently compressed in the space lettered R to force the oil intothe inlet d of the oil-ejecting tube D and into the oil-ejecting pipe D,and which will continue to fiow until the finger moves from the orificeh, when the air, escaping from the interior of the can, relieves thesurface of the oil from pressure and thus stops the fiow of the oil.

Instead of having an open orifice at 7L there may be, of course, a smallvalve supplied,

which can be depressed by the finger when it is desired to permit theescape of the confined air in the can, and thus to check the flow of theoil. A

The air-pump cylinder G instead of being placed within the can may, ofcourse, be attached `to the can outside thereof, when the same eilectwill be produced, although itis more convenient to have it as indicated.The oil-ejecting pipe D is also rotatable, as mentioned, for the purposeof withdrawal, as well as to turn the bent spout over the top of the canwhen the can is not in use.

What I claim as my invention is l. In an' oil can and lamp filler, thecombination of the gutter z5; eccentric openingS; oil ejecting pipe D;pin s; waste oil chamber T; and oil ejecting tube D; substantially asdescribed and for the purpose specified.

2. In au oil can and lamp filler, the combination with the can A, of theair pump cylinder G; cap g; hollow piston rod Il; piston head I; airvalve L; pipe V; air chamber IV; valve L; hollow stem F; flexible tubeF; and air inlet pipe E, substantially as described and for the purposespecified.

I-n an oil can and lamp filler, the combination of the can A; airinlet pipe E; flexible tube F; hollow stem F hollow piston rod Il;gnttert; eccentric opening S; pin s; oil ejecting pipe D; waste oilchamber T; oil ejectiug tube D; screw cap C; air pump cylinder G; cap g;piston head I; air valve L; packing U; spring c; flange K; pipe V; airchamber W, and valve L', substantially as described and for the purposespecified.

4. In an oil-can and lamp-filler, the combination of an oil-can, anair-pump cylinder, a hollow piston-rod II communicating with saidoil-can and working in said pump-cylinder and having a piston-head I andair-valve L, air-chamber WV and valve L', and a pipe V affordingcommunication between said chamber W and the upper'part of the air-pumpcylinder, whereby air is drawn through said pipe V, and by means of thepiston-head I and valves L and L is forced through the hollow piston-rodII into the oil-can, substantially as described.

5. In an oil-can and lamp-filler, the combination of an oil can, a pumpcylinder and a .hollow piston-rod, a fiexible air-passage between theinterior of the can and the interior of said hollow piston-rod,means forpumping air through the piston-rod and flexible air passage so as tocompress the air above the oil, and an oil ejectiug pipe, substantiallyas described and for the purpose specified.

6. In an oil-can and lamp filler, the combination of the can A, fiexibletube F, airpump cylinder G, hollow piston-rod Il, and means for pumpingair through the flexible ICO IIO

interior of the can above the oil; and the oil to and open at the other,means for admitting air below the piston-head on the up stroke and aexible tube communicating with the hollow piston-rod and with theinterior of the can above the oil, substantially as described.
